Problem 3 (16 points) A well of unknown depth has a wire stretched across the opening. The wire is placed under tension by an 8.16 kg mass hanging from a pulley at one end. The other end is attached to a vibrating source. The original length of the wire is 2.50 m with a mass of 75.0 g. The distance between the pulley and the vibrating source is 2.20 m. The second harmonic of the wire produces the third harmonic in the well. The speed of sound is 343 m/s and $g = 9.80 \text{ m/s}^2$ a) (4 points) What is the fundamental frequency of the wire? b) (4 points) What is the depth of the well? c) (4 points) What tension on the wire would be required to produce the second harmonic in the well? d) (4 points) If the fundamental frequency of the wire was 12.0 Hz, what would the speed of sound be in order that the second harmonic of the wire still produces the third harmonic in the well?
